Abstract
The present invention relates to an optical cross-connect apparatus supporting plural directions, and provides a method of effectively performing an alarm indication by a node supervisory unit of the optical cross-connect apparatus. The node supervisory unit includes an alarm indication information storage unit that manages a management table for each of the plural directions. The management table manages not only received alarm indication information but also 'internal WSS input/output port optical fiber connection state', 'WSS optical path setting state on DROP/THROUGH selection side', “transponder destination location”, and “destination direction”, with respect to each direction. Then, a process flow is added to match received FDI information with the management information stored in the management table for each direction, and to specify an alarm destination.
